after upgrading my system i was not able to do a graphical login via kdm. So i upgraded kde to kde 4.10, but still the same. In my local .xsession-error i see following:

kded(6020): Communication problem with "kded" , it probably crashed.
Error message was: "org.freedesktop.DBus.Error.NoReply" : " "Message did not receive a reply (timeout by message bus)" "

after posting here i changed my "search strategy".
First i was focused on the "Communication problem with "kded" , it probably crashed" error, for what i couldn't find a solution.
Since posting here i searched for "ksmserver: error while loading shared libraries: libpulsecommon-4.0.so: cannot open shared object file: No such file or directory" which i thougt was just a consequence of the first error. But here i found some helpfull hint's. So after installing libpulse0 and pulseaudio i'm able to log in graphically again.
